That's Kenneth Arthur from Fieldgulls, he also did a podcast thing on Seahawks Draft Blog recently. He's a Seahawks fan, obviously.
He's pretty unique and I think his humor is lost on many unfortunately. Kind of reminds me of Kenny Mayne some (who's also from Seattle) in that he's very dead pan and a little strange but very clever and witty just the same. This is how Mayne got his gig at ESPN:
ESPN hired Mayne in 1994 after Mayne had sent ESPN a note inquiring whether the network would hire him. The note simply asked to check a box, including one option that read, "We'll hire you when there's an ESPN5."
Very Kenneth Arthur like.
